Pike v8.0 release 31 running Hilfe v3.5 (Incremental Pike Frontend)
> (<"1">)->any;
Compiler Warning: 1: Indexing on illegal type.
Compiler Warning: 1: Got     : multiset(string(49..49)).
Compiler Warning: 1: Index   : string(97..121).

This piece of code is from Roxen 6.0 base_server/roxen.pike
around line 7455:

    "    if ((user || (user = authmethod->authenticate(id, userdb_module)))\n"
    "        && ((%[0]s->any && sizeof(user->groups())) ||\n"
    "            sizeof(mkmultiset(user->groups())&%[0]s)))",

And it is triggered by a sole "allow group=1" security rule for some
filesystem module.
I presume this needs to be fixed in Pike, as opposed to in Roxen.
